Big problem!

Lightroom stuck on gallery page, has been loading for 3 days! Can't close lightroom, not even when forcing it (use Mac). Just doesn't respond to anything except hiding the window. I've tried deleting the program by dragging it to my bin or trough the creative cloud webpage, same with updating, but nothing works! If anyone has any clue on what to do, please let me know! I need it tomorrow 😬.
